My grandpa told me a story,that was very interesting.One hot summer day,a fox was taking walk when he noticed a bunch of grapes that just turn ripe,hanging high above.He felt estreme thirsty,so he took a step back,then running forward and jumped,but he missed the grapes.Though he was a bit disappointing,but he made up his mind to try again.He tried with all his strengths.But again he missed the grapes.Again and again he tried,but he gave up on the end.And he walked away with his nose in the air,saying,"I didn't want those older grapes anyway.I'm sure they are sour."
